Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of the embodiments of the present disclosure, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure, presented in the figures, is not intended to limit the scope of the claimed disclosure, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The term "and/or" herein merely describes an associative relationship, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.
With the continuous development of the application technology of electronic devices, keyword search has been widely applied in different service scenarios. In some electronic device applications, when a user inputs a search keyword, a part of words in a text associated with the search keyword is often highlighted in order to facilitate display of important information in the text. For example, in a search interface of a mobile phone address book or an address book of an a application, when a user inputs "zhaozh", the search interface may display a name "zhao zhen" or "zhao zhi" associated with "zhaozh" and highlight the name.
Research shows that the highlighting form in the prior art is too single, for example, when a user inputs a search keyword "zhao zh" or "zhao zh", the two search modes are obviously different, and a separator (for example, a space) may exist in the search keyword, whereas the highlighting form in the prior art for the two search modes is the same, for example, the change of the same font color or the font thickening, the display mode is not flexible enough, the pertinence is lacked, and the user experience is not good.
Based on the above research, the present disclosure provides a text search method, which obtains search information input by a user, and then determines whether a search mode of the search information is an exact match search or a fuzzy match search, wherein the fuzzy match search indicates that a separator exists in the search information, the exact match search indicates that no separator exists in the search information, in a case that the search mode of the search information is the fuzzy match search, first highlighting is performed on first target texts corresponding to the search information at both ends of the separator, in a case that the search mode of the search information is the exact match search, second highlighting is performed on second target texts corresponding to the search information, wherein the second highlighting is different from the first highlighting, and thus, aiming at different search modes of the user, the highlight display modes of the target text are different, so that the diversity of the highlight display modes is increased, the prompt for distinguishing the key information corresponding to different search modes by the user is facilitated, and the user experience is improved.
To facilitate understanding of the present embodiment, first, a text search method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the text search method provided in the embodiments of the present disclosure is generally an electronic device with certain computing capability, and the electronic device includes, for example: a terminal device, which may be a mobile device, a user terminal, a handheld device, a computing device, a vehicle device, a wearable device, or the like, or a server or other processing device. In some possible implementations, the text search method may be implemented by a processor invoking computer readable instructions stored in a memory.
Referring to fig. 1, a flowchart of a text search method provided by the embodiment of the present disclosure is shown, where the method may be applied to the electronic device, or applied to a local or cloud server. The text search method shown in fig. 1 includes the following S101 to S104:
s101, acquiring search information input by a user.
For example, the mode of inputting the search information by the user may be an input mode such as a keyboard input, a touch input, or a mouse input for the computer terminal, and an input mode such as a keyboard input, a touch input, or a trackball input for the smart mobile terminal.
The search information comprises a search keyword input by a user on a search interface of the terminal, and the search keyword can be a single character or a character string. The language type of the search keyword may include, but is not limited to, numeral, chinese, english, japanese, french, german, etc. For example, when the user searches for the name "zhao zhen" in the address book of the application a, the user may input the search information "zhaozhen" in the search interface of the address book, may also input "zhaozh", and may also directly input the chinese character "zhao zhen", which is not limited herein.
S102, judging whether the searching mode of the searching information is accurate matching searching or fuzzy matching searching; wherein the fuzzy matching search means that a separator exists in the search information, and the exact matching search means that a separator does not exist in the search information.
For example, the exact match search is a search mode in a case that the user completely knows a target text that needs to be searched, that is, the search information input by the user is continuous without any break or separator, for example, the search information may be "lixiaoming", or "lixiaom", or the like. The fuzzy matching search is a condition that a user may forget a certain word of a target text to be searched or input by mistake, a separator exists in the input search information, for example, the search information may be li ming, or li, ming, the user may forget a small word in friend names 'li ming' in an address book, and the separator 'space' is used for replacing the small word when the search information is input. Therefore, before highlighting the target text, it is necessary to determine whether the search mode of the user is an exact match search or a fuzzy match search.
And S103, under the condition that the search mode of the search information is the fuzzy matching search, performing first highlight display on first target texts corresponding to the search information at the two ends of the separator.
Illustratively, for example, the search information input by the user is "zhao zh", and the first target text may be a word of "zhao" and "true" in the friend name "zhao" in the address book of the user terminal. The highlight display mode can be a bold font of the target text, and can also be a change of the font display color of the target text so as to be distinguished and displayed relative to the common text, and further give a corresponding prompt to the user. For example, for a bold face of a bold text, highlighting can be achieved by changing the color of the font, and for a font with a special color, highlighting can be achieved by changing the thickness of the font. In some embodiments, the highlighting of the target text may also be achieved by other means, which are not limited herein.
For example, referring to fig. 2, a schematic diagram for performing a first highlighting on a first target text provided by an embodiment of the present disclosure is shown, where "zhao zh" is search information a, "zhao zhen", "zhao", and "zhao" in the zhao and "zhao", and "zhi" is a first target text b corresponding to "zhao" and "zh" at two ends of a "space", and the first target text is highlighted in a manner of "bold font", that is, the fonts of "zhao" and "zhao" in "zhao zhen", i.e., the fonts of "zhao" and "zhi" in "zhao zhen", are bold compared with other common fonts, so that a user can see important information in the target text conveniently.
S104, under the condition that the searching mode of the searching information is the accurate matching searching, second highlighting is carried out on a second target text corresponding to the searching information; wherein the second highlighting is in a different display manner than the first highlighting.
In this step, the search information is continuous without a separator in the middle, such as "zhaozh", and the corresponding second target text may be "zhao" or "zhao" and the second highlight may be displayed in a different manner from the first highlight. For example, if the first highlighting display mode is "font bolding", the second highlighting display mode may be "changing font color"; for another example, if the first highlighting is displayed in a "font is red", the second highlighting may be displayed in a "font is yellow". The display mode may be other modes, and is not limited herein.
According to the method and the device, the highlight display modes of the target text are different according to different search modes of the user, the diversity of the highlight display modes is increased, the user can distinguish prompts of key information corresponding to different search modes conveniently, and the user experience is improved.
With reference to the above S103, referring to fig. 3, a flowchart of a specific method for performing first highlighting on a first target text provided by the embodiment of the present disclosure includes the following S1031 to S1037:
and S1031, obtaining the search field associated with the search information.
For example, when the user inputs search information, the user terminal may receive the search information input by the user through the search interface, and search and acquire a search field or context with the search information from a local database according to the search information. Specifically, whether the search field or the context is obtained is combined with a specific service scenario, which is not limited in the embodiment of the present disclosure.
For example, when the search information input by the user on the address book search interface of the application program a is "zhaozh", the user terminal may obtain a search field containing a Chinese character corresponding to "zhaozh" in the address book of the application program a, such as "zhao zhengyang" and "zhangdong", that is, all the friend names corresponding to "zhaozh" in the address book.
S1032, judging whether the search information is first type information or not, wherein the first type information comprises pinyin; if yes, go to step S1033; if not, go to step S1036.
For example, the first type information may be pinyin or english, and is not limited herein, and the following methods of the present disclosure are mainly described by taking pinyin as an example.
S1033, constructing a first mapping of the search information and the position of the Chinese character corresponding to the search information in the search field.
For example, in the case that the search information is pinyin, for example, if the search information input by the user is "zhao sh", and the corresponding search field is "zhao winner", the starting and ending positions of "zhao" in "zhao winner" corresponding to "zhao" are [0,0], and a first mapping of "zhao" and [0,0] is constructed. In this embodiment, it is assumed that the position of the chinese character in the search field is from 0, for example, the starting and ending positions of "zhao" in "zhao victory" are [0,0], "victory" in "zhao victory" is [1,1], "zhao victory" in "zhao victory" is [0,1 ]. In other embodiments, the position of the chinese character in the search field may be defined in other ways, and is not limited herein.
S1034, determining a first start position and a first end position of the search information in the search field, based on the first mapping.
Illustratively, the first start position and the first end position of the search information "zhao" in the search field "zhao" are [0,0], and the first start position and the first end position of the search information "sh" in the search field "zhao" are [1,1 ].
In some embodiments, in a case where there are multiple search keywords in the search information, there may be a case where the first search keyword includes the second search keyword, for example, the search information is "zhao zh", the first search keyword "zhao" includes the second search keyword "zh", where it is necessary to add 1 to the end position of "zhao" as the start position of "zh", for example, the position index of "zhao" is [0,0], and the position index of "zh" is [1,1 ]. Therefore, repeated highlighting can be avoided, and processing steps can be reduced.
S1035, traversing the search field, determining the first target text according to the first start position and the first end position, and performing the first highlighting on the first target text.
For example, if the search information is "zhao sh", two search fields "zhao sheng" and "zhao yang" are searched in the address book, then the first target text of "zhao sh" in the search field "zhao" is "zhao sheng", and the first target text of "zhao sh" in the search field "zhao sheng" is "zhao", and the search interface highlights "zhao sheng" and "zhao sheng".
In the embodiment of the disclosure, the positions of the search information and the Chinese characters corresponding to the search information in the search field are mapped to be highlighted, so that the highlight display accuracy is improved, and the search modes of various situations can be processed.
S1036, determining a second starting position and a second ending position of the search information corresponding to the search field.
For example, in the case that the search information is a chinese character, for example, because there is no need to construct a mapping of positions of the pinyin and the chinese character corresponding to the pinyin in the search field, the second start position and the second end position of the chinese character corresponding to the search field may be directly obtained by a preset method. For example, the search information is "lie small", the search field is "lie diming", and then the "lie small" can be directly obtained to be [0,1] at the second start position and the second end position of the search field "lie diming". The preset method may be a java method or other methods, and is not limited herein.
S1037, traversing the search field, determining a first target text according to the second starting position and the second ending position, and performing first highlighting on the first target text.
Illustratively, such as the example in step S1036, when the first target text corresponding to [0,1] is "lie small", the "lie small" is highlighted.
In the embodiment of the disclosure, even if the search information is not the first type of information, the first target text can be highlighted, so that the search mode and the highlighting method are more comprehensive, and the application range is expanded.
With reference to the above S1033, referring to fig. 4, a flowchart of a method for constructing a first mapping of search information and positions of chinese characters corresponding to the search information in a search field provided by an embodiment of the present disclosure includes the following S10331 to S10333:
s10331, converting the search field into pinyin, and constructing a second mapping between each Chinese character in the search field and the pinyin corresponding to each Chinese character.
It can be understood that, in the case that the search information is pinyin, in order to construct the first mapping, the search field needs to be first converted into pinyin, and a mapping relationship between each chinese character in the search field and the pinyin corresponding to each chinese character is constructed, and in the case that polyphones may exist, one chinese character may Map multiple pinyins, and a data structure is created as Map < String, List < String > wordpinmap for storing the mapping between each chinese character in the search field and pinyin.
In this embodiment, since the search information is not only a search keyword due to the fuzzy matching search, the pinyin for the first search keyword must start with the first letter of a chinese character, but other search keywords may not start with the first letter of a chinese character, and therefore the first search keyword and other search keywords that follow need to be processed separately. Firstly, aiming at a first search keyword, a mapping relation between a Chinese character in a search field and pinyin which is corresponding to the Chinese character and starts with an initial letter is constructed, for example, the search field is 'li Xiaoming', and a mapping between 'li' and 'li' is constructed. And aiming at other keywords behind the first search keyword, constructing a mapping relation between the Chinese characters in the search field and pinyin starting from any letter corresponding to the Chinese characters, such as constructing a mapping between 'small' and 'ao', and also a mapping between 'small' and 'iao'. And then the two mappings are stored in the wordpinymap.
In some embodiments, for a first search keyword and other search keywords in the case of fuzzy matching search, when a start position and an end position are obtained, there are cases where the start position of the other search keywords is less than or equal to the end position of the first search keyword, for example, the start and end positions corresponding to "chen" are [0,0], and the start and end positions corresponding to "enli" are [0,1 ].
In some embodiments, before the search field is converted into pinyin, there may be a case where an expression exists in the search field, and the determination is made in such a manner that the lengths of the expression and the chinese character are different, and it is necessary to determine whether the character in the search field is an expression. If the expression is the expression, the expression is directly stored into the wordpinymap without conversion; if the Chinese characters are Chinese characters, the Chinese characters need to be converted into pinyin and then stored in the wordpinymap. Therefore, the conversion efficiency and the conversion precision can be improved.
In some embodiments, where the search information is pinyin, the user's search type may be the full pinyin of the pinyin, such as "lixiaoming," or the first letter of the pinyin, such as "lxm. Correspondingly, when the search field is converted into pinyin, the search field can be converted into pinyin full pinyin and stored in the full pinyin Set < String > quanpin, and then a second mapping between the Chinese characters in the search field and the corresponding full pinyin of the Chinese characters is constructed, such as the "li" mapping; it is also possible to convert the search field to the first letter of the chinese character corresponding to the pinyin and store it in the Set of first letters < String > shouzimu, and then construct a second mapping between the chinese character in the search field and the first letter corresponding to the chinese character, such as the "li" mapping "l. Therefore, the target text corresponding to the full spelling input by the user can be highlighted, the target text corresponding to the first letter input by the user can be highlighted, and the search range is widened.
S10332, constructing a third mapping between each Chinese character in the search field and the position of each Chinese character in the search field.
Illustratively, after the mapping between each chinese character and the pinyin corresponding to each chinese character in the search field is constructed, the mapping relationship between each chinese character and the position of each chinese character in the search field also needs to be constructed, for example, in the search field "lisgming", lie "forms a mapping with [0,0], small" forms a mapping with [1,1], and "lisgmi" forms a mapping with [0,1], and a data structure is created as Map < Integer, String > indexmap for storing the mapping relationship between each chinese character and the position of each chinese character in the search field.
S10333, constructing the first mapping based on the search information, the second mapping, and the third mapping.
Illustratively, based on the second mapping and the third mapping in the above steps, a mapping relationship of positions of the pinyin and the chinese characters corresponding to the pinyin in the search field can be constructed, and a data structure of Map < String, wordlndex > pinyindinxmap is created for storing the mapping relationship of the positions of the pinyin and the chinese characters corresponding to the pinyin in the search field. For example, "li xiao qiang" is converted into pinyin, and then "lixiaoqi", "l" and "li" are part of the pinyin of the "li" word, so the starting and ending positions corresponding to the two character strings are both [0,0], "lix" is [0,1], "x" is [1,1 ]. In addition, it should be noted that the initial letter of each pinyin is only the first letter of any Chinese character in the search field, for example, "ix" does not appear. Then, based on the mapping relation, the starting position and the ending position of the search information in the search field can be obtained to determine the target text, and then the target text is highlighted.
In the embodiment of the disclosure, the first mapping is further constructed by constructing the second mapping and the third mapping, so that the corresponding relation between the search keyword in the search information and the position of the search keyword in the search field is realized, and the accuracy of the target text highlight display method is ensured.
Referring to fig. 5, a logic flow diagram of a highlighting method provided by the embodiment of the present disclosure includes the following steps S110 to S123:
s111, judging whether the searching mode is accurate matching searching or fuzzy matching searching, and if the searching mode is accurate matching, executing S112; if the fuzzy match is true, S116 is executed.
S112, judging whether pinyin searching is passed, if yes, executing S113; if not, go to S114.
S113, mapping of the pinyin started by the initial letter and the position of the Chinese character corresponding to the pinyin in the search field is constructed.
S114, acquiring the position of the search keyword in the search field.
And S115, carrying out second highlighting on the second target text corresponding to the search keyword.
S116, judging whether pinyin searching is passed, if yes, executing S117; if not, S121 is executed.
S117, judging whether the keyword is the first search keyword, if so, executing S118; if not, go to step S119.
S118, mapping of the pinyin started by the first letter and the position of the Chinese character corresponding to the pinyin in the search field is constructed.
S119, mapping of the pinyin initiated by any letter and the position of the Chinese character corresponding to the pinyin in the search field is constructed.
And S120, acquiring the position of the search keyword in the search field and combining the overlapped positions.
S121, acquiring the position of the search keyword in the search field.
And S122, performing first highlighting on the first target text corresponding to the search keyword.
